whether any technology lessons to be drawn from this years election? >> it's always hard to reason from one event. the winners get to write history and the losers think about the next election. there's no question the obama campaign, had a technology strategy that helped elect the president. they had little processors and targeted programs and send out the vote. to me the way to say this is governments are going to change, too. because on the one hand governments have an awful time delivering services. now we can measure the. if someone as you give me some money to donate rice to the following village, we cannot check whether the rice got there. a check and balance on sort of the corruption. and we can test the effectiveness of programs. to give you some of the more worrisome examples, governments can know where people really are and governments can figure out where people report what they're doing versus what they're actually doing. there are all sorts of worrisome scenarios that you can imagine, the slippery slope. i'll pick one in britain. in london
